project 8054 on an ati, can I make it stop?

alright, I have been folding fine for the last few days, and suddenly the folding at home client/servers decide to start trying to give me nvidia WUs. How can I make it stop? can I even make it stop? no folding has happened for the last day

The reason I know that these are nvidia WUs is that it is trying to access core_15, which to my knowledge is an nvidia/fermi core. What can I do?
